IMPROVEMENT IN CORSET-CLASPS.

Speciiication forming part of Letters Patent No. 149,206, dated March 31, 1874; application led February 11, 1874.

To ali whom it may concern:

Be it known that I, THOMAS I3. DE FonEsT, of Birmingham, in the county of New Haven and State of Connecticut, have invented a new Improvement in Corset Clasps; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent,.in-

Figures l and 2, front views of the two parts of a corset-clasp; Fig. 3, a partial side view and longitudinal section; and in Fig. 4, a transverse section.

This invention relates to an improvement in what are known to the trade as corsetclasps, and consists in combining with a lon gitudinal foundation a wire coiled spring, through which the longitudinal foundation is placed, and the coiled spring rolled down thereon, as more fully hereinafter described.

A is the longitudinal foundation, preferably a spring, which is made about one-fourth the width of common steels, and over this a coiled spring, B, (single or more,) is placed, made sesses the required amount of elasticity with. a very greatly increased amount of flexibility,

rendering it impossible to break the clasps, and as the coil B may be made from non-corrosive wire, the usual protection to prevent this is avoided.

I claim as my invention- A corset-clasp formed from a longitudinal foundation-strip inclosed Within a coiled-wire spring, which is rolled down on the said longitudinal foundation, the coils preserving their circular form, substantially as described, and provided with tips and hooks and eyes.
